Hi Jagan,
On a mx7dsabresd board I am not being able to probe the soft_spi driver using DM with mainline U-Boot.
Device tree used is the same one as used in the kernel (imx7d-sdb.dts).
soft_spi driver is used to communicate with a I/O expander (supported via CONFIG_DM_74X164), but it can't get probed:
spi 0 [ ] soft_spi |-- spi4
which causes the the I/O expander to not get probed as well.
What needs to be done for soft_spi to get probed in DM?
Hope you have aliases spi0 = &spi4 here?
